# How to contribute
We welcome contributions to WebDNN. This document describes the procedures and rules.

Kinds of contributions will be one of the following, but not restricted to:
- Bugfix
- Implementation of a layer
- Implementation of a converter from a deep learning framework
- Improvement of performance
- Documantation

For new layer implementation, at least WebAssembly backend implementation is required. WebGPU backend can only be tested on Mac, so it is not mandatory.

# Testing
If you have added some features, implementing tests corresponding to them is recommended.

`test/webdnn_test` is for tests which can be completed within graph transpiler. `test/runtime` is for tests which generates graph descriptor and compares its behavior on web browsers.

See how to run test commands in `test/README.md`.

# Pull Request
